Called no name and no message

Repeated automated call from some organization purporting to arrange grant money. Two days in a row to a Federal Business Office. These people can't be real bright.
Options, "press number 1 to speak with an agent, press number 2 to be removed from their call list". Neither option works. Tried to return the call but message says the number cannot be reached as dialed.

caller does not say anything - then hang up

Call office and cell.  No message and just hung up.

Got an automated call from this number, it is calling a state government agency in WA. Tried pressing "1" to get them to take our number off their dialer...person answered, when I said what I wanted, they hung up.
